Abstract
Abstract A coextruded chewing gum is provided which includes an extruded center portion surrounded by and bonded to an extruded outer shell portion. The center portion of the coextruded chewing gum may contain increased amounts of flavor, substantially greater than that ordinarily employed in chewing gums of conventional structure, and may have a different density than the outer shell portion to provide a textural difference upon chewing.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
176 words
A coextruded chewing gum having improved flavor comprising from about 40 to about 75% by weight of an extruded soft gum core portion and from about 25 to about 60% of an outer shell portion formed of chewing gum and extruded simultaneously with said core portion, said core portion formed of chewing gum containing from about 1.5% to about 2% by weight flavor based on the total weight of the coextruded chewing gum, and from about 2.2 to about 4% by weight flavor based on the weight of the core portion, said outer shell portion having a density different than the density of the chewing gum of said core portion, and containing from about 0.3 to about 1.2% by weight flavoring based on the weight of the shell portion, said shell portion being bonded by means of said coextrusion to said core portion to provide a support and protective barrier therefor to retain said flavor in said core portion and retard migration of flavor from said core portion to the outer surface of said shell portion.
Claim 2
Dependent Claim
176 words
A coextruded chewing gum having improved flavor comprising from about 40 to about 75% by weight of an extruded soft gum core portion and from about 25 to about 60% of an outer shell portion formed of chewing gum and extruded simultaneously with said core portion, said core portion formed of chewing gum containing from about 1.5% to about 2% by weight flavor based on the total weight of the coextruded chewing gum, and from about 2.2 to about 4% by weight flavor based on the weight of the core portion, said outer shell portion having a density different than the density of the chewing gum of said core portion, and containing from about 0.3 to about 1.2% by weight flavoring based on the weight of the shell portion, said shell portion being bonded by means of said coextrusion to said core portion to provide a support and protective barrier therefor to retain said flavor in said core portion and retard migration of flavor from said core portion to the outer surface of said shell portion.
Claim 3
Dependent Claim
31 words
The coextruded chewing gum as defined in claim 1 wherein said core portion is present in a weight ratio to said outer shell portion of from about 0.05:1 to about 9:1.
Claim 4
Dependent Claim
19 words
The coextruded chewing gum as defined in claim 2 wherein said ratio is from about 0.67:1 to about 3:1.
Claim 5
Dependent Claim
44 words
The coextruded chewing gum as defined in claim 1 wherein the chewing gum forming said core portion is comprised of synthetic gum base and is free of antioxidants, said outer shell portion protecting said core portion from thermal and other types of oxidative degradation.
Claim 6
Dependent Claim
53 words
The coextruded chewing gum as defined in claim 1 wherein one of said core portion and said outer shell portion is formed of chewing gum which provides fast flavor and sweetness release, while the other of said portions is formed of chewing gum which provides slow initial but prolonged sweetness or flavor release.
Claim 7
Dependent Claim
144 words
A method forming a coextruded chewing gum as defined in claim 1, which comprises providing a chewing gum for said core portion containing from about 2.2% to about 4% by weight flavor based on the weight of said core portion, and a chewing gum for said outer shell portion having a density different than the density of the chewing gum of said core portion and containing from about 0.3 to about 1.2% by weight flavoring based on the weight of said shell portion, extruding a rope of said chewing gum comprising said core portion, and simultaneously extruding a hollow rope of said chewing gum comprising said outer shell portion about said extruded core portion to completely surround and form a protective barrier around and bonded to said core portion and thereby retard migration of moisture from said core portion to said outer shell portion.
